Description

Technical Field

[0001] This utility model relates to the field of building-related technology, and in particular to a detachable steel edge formwork for composite floor slabs. Background Technology

[0002] In building structural engineering, the inverted curb structure, as an important waterproof, moisture-proof, and area separation structure, is widely used in indoor and outdoor floor slabs such as roofs, bathrooms, kitchens, and balconies. Currently, the inverted curb position on roofs and in many indoor composite floor slabs is often higher than the floor slab. Because the conventional edge plates of composite floor slabs are made of galvanized steel plates only a few millimeters thick, their rigidity is insufficient, and they can only reach the floor slab height. Positions higher than the floor slab require secondary formwork and pouring after the floor slab is formed. Secondary formwork is costly in terms of labor, and secondary concrete pouring carries the risk of cracking. Existing technologies offer formwork structures for one-time molding of concrete inverted curb structures, but these formwork structures often have shortcomings. These formwork structures typically involve complex assembly and disassembly processes, require high operational skills, and have poor construction convenience. Furthermore, their support and reinforcement systems are often inadequate, making them prone to deformation, displacement, or grout leakage during concrete pouring. This results in difficulties in ensuring the dimensional accuracy, verticality, and surface quality of the inverted curb, leading to generally poor molding results. Utility Model Content

[0021] Reference Figures 1 to 7According to a first aspect of the present invention, a detachable steel-edged formwork for a combined floor slab includes an outer formwork 100, an inner formwork 200, a limiting component, and a cover plate 300. The outer formwork 100 includes a first side plate 110, a first transverse edge 120, and a second transverse edge 130. The first transverse edge 120 is located at the top of the first side plate 110 and extends inward. The second transverse edge 130 is located at the bottom of the first side plate 110 and extends outward. The second transverse edge 130 is used for detachable connection with a steel beam 500 via fasteners. The inner formwork 200... The system includes a second side plate 210 parallel to the first side plate 110 and a third transverse side 220. The third transverse side 220 is located on the top of the second side plate 210 and extends outward. The outer template 100 and the inner template 200 are detachably mounted on the limiting component, and the limiting component can restrict the outer template 100 and the inner template 200 from moving in opposite directions. The cover plate 300 is detachably connected to the first transverse side 120 and the third transverse side 220 by fasteners. The cover plate 300 can cover the upper opening between the outer template 100 and the inner template 200. The outer formwork 100 can be positioned by abutting against the steel beam 500 structure via the second horizontal edge 130 and is detachably connected by fasteners, facilitating easy assembly and disassembly. The outer formwork 100 and inner formwork 200 structure can form a reverse curb in one step. Furthermore, the first horizontal edge 120 at the top of the outer formwork 100 and the third horizontal edge 220 of the inner formwork 200 can be positioned by abutting against the cover plate 300 and are detachably connected by fasteners, preventing top bulging and improving the forming effect. The inner formwork 200 and outer formwork 100 are restricted by limiting components, ensuring accurate lateral dimensions. Moreover, the above structure can be assembled and disassembled using fasteners, facilitating construction. Specifically, the outer formwork 100 can be set in a Z-shape, with the first side plate 110 and the second side plate 210 both set vertically. The first side plate 110 and the second side plate 210 are spaced apart to define the pouring space. The second horizontal edge 130 at the bottom of the first side plate 110 can abut against the top surface of the steel beam 500 structure, and the second horizontal edge 130 can be provided with connecting holes for bolt connection. The floor slab bottom formwork can extend to the first side plate 110, and the second side plate 210 and the first side plate 110 can be connected by a limiting component. The limiting component can prevent the first side plate 110 and the second side plate 210 from moving in opposite directions to facilitate pouring and forming. The specific structure of the limiting component is not limited here. The top of the second side plate 210 is aligned with the top of the first side plate 110, and the third horizontal edge 220 is arranged horizontally opposite to the first horizontal edge 120 to facilitate abutment with the cover plate 300. The cover plate 300 can be bolted to the first horizontal edge 120 and the second horizontal edge 130. The cover plate 300 effectively prevents bulging. Furthermore, the cover plate 300, the outer template 100, and the inner template 200 can all be removed by unscrewing bolts, making construction convenient and resulting in a good molding effect.

[0022] It is understandable that the first horizontal edge 120 and the second horizontal edge 130 can be bent or welded to the first side plate 110. Similarly, the third horizontal plate can be connected to the second side plate 210 by bending or welding.

[0023] Reference Figure 1 and Figure 4 In some embodiments of this utility model, the cover plate 300 has a downward-opening groove 310. The inner sidewall of the groove 310 abuts against the first side plate 110 and the second side plate 210, respectively, and the bottom wall of the groove 310 abuts against the first horizontal edge 120 and the second horizontal edge 130. Specifically, the cover plate 300 can be roughly set as a C shape. During installation, the groove 310 can be positioned and inserted into the top of the outer template 100 and the inner template 200. The inner sidewall of the groove 310 can abut against the outer sidewall of the first side plate 110 and the inner sidewall of the second side plate 210, which facilitates assembly and positioning. It is understood that the cover plate 300, the first horizontal edge 120 and the second horizontal edge 130 can be provided with aligned connecting holes for bolt or screw connection, or the cover plate 300 and the horizontal edge can be directly connected by nails.

[0024] Reference Figure 1 and Figure 3 In some embodiments of this utility model, the limiting component is provided as at least a plurality of first tie members 410. The first tie members 410 can reinforce the outer template 100 and the inner template 200, thereby offsetting the lateral pressure and buoyancy on the template generated during concrete pouring, so as to improve the molding accuracy.

[0025] Reference Figure 3 In some embodiments of this utility model, the first tie member 410 includes a steel bar 411 and two nuts 412. One end of the steel bar 411 passes through the inner template 200, and the other end passes through the outer template 100. Both ends of the steel bar 411 are threadedly connected to nuts 412. When a parapet wall is set at the edge of a composite floor slab, the conventional edge sealing plate itself has insufficient rigidity. If the concrete is poured too high, the formwork will burst due to insufficient lateral rigidity. By setting the first tie member 410, the lateral restraint force can be improved. Specifically, the steel bar 411 can be set as a cylindrical bar, and threads can be machined near both ends of the steel bar 411. The nuts 412 are connected to the threads. The outer nut 412 can abut against the outer side of the outer template 100, and the inner nut 412 can abut against the inner side of the inner template 200 to clamp the two templates.

[0026] Reference Figure 1 and Figure 7In some embodiments of this utility model, the bottom of the second side plate 210 extends to the top of the floor slab, and the inner formwork 200 also includes a fourth horizontal edge 230. The fourth horizontal edge 230 is located at the bottom of the second side plate 210 and extends inward. A second tie member 420 is provided between the fourth horizontal edge 230 and the steel beam 500. Specifically, the bottom of the second side plate 210 may be provided with a fourth horizontal edge 230, so that the inner formwork 200 may also be Z-shaped. The fourth horizontal plate may abut against the top of the floor slab, and the fourth horizontal plate is connected to the steel beam 500 at the bottom of the floor slab through the second tie member 420. The structure of the second tie member 420 may be the same as that of the first tie member 410. Through the second tie member 420, a constraint force in the height direction can be provided for the inner formwork 200, which can also prevent bulging.

[0027] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the top of the steel beam 500 is provided with an outwardly extending horizontal support member 510. The support member 510 is used to support the bottom formwork of the floor slab. A first diagonal brace 520 is also provided between the support member 510 and the steel beam 500, and a third horizontal side 220 is connected to the support member 510. Specifically, the support member 510 can be set as an angle steel. The outwardly extending angle steel can support the cantilever floor slab and realize the inverted sill casting of the cantilever floor slab. The support member 510 and the steel beam 500 are reinforced by the first diagonal brace 520. The third horizontal side 220 can abut against the support member 510 and indirectly connect to the steel beam 500.

[0028] Reference Figure 1 and Figure 5 In some embodiments of this utility model, a leak-proof base plate 600 is also included, which is installed between the third horizontal edge 220 and the floor slab bottom formwork. Specifically, the leak-proof base plate 600 can be made of a relatively soft aluminum-zinc coated thin steel plate, and can be placed between the third horizontal edge 220 and the floor slab bottom formwork to seal the gap between the two components and prevent slurry from flowing out of the gap.

[0029] Understandably, the leak-proof base plate 600 can also be placed between the third horizontal edge 220 and the support member 510.

[0030] Reference Figure 5 In some embodiments of this utility model, the leak-proof base plate 600 includes a vertical portion 610 and a horizontal portion 620. The vertical portion 610 is located at the outer end of the horizontal portion 620. The third horizontal edge 220 can press the horizontal portion 620 tightly against the floor slab bottom mold, and the vertical portion 610 abuts against the outer side of the third horizontal edge 220. Specifically, the leak-proof base plate 600 can also be provided with an L-shaped plate, formed by stamping and bending. The horizontal portion 620 is a horizontal plate, and the vertical portion 610 is a bent vertical plate. The horizontal portion 620 is placed at the bottom of the third horizontal edge 220, and the vertical portion 610 is located outside the third horizontal edge 220 to improve the leak-proof effect.

[0031] Reference Figure 1 In some embodiments of this utility model, a second diagonal brace 140 is provided between the outer side wall of the outer template 100 and the support member 510. Specifically, the second diagonal brace 140 can be connected between the outer side wall of the outer template 100 and the support member 510 by detachable fasteners to further increase the constraint force.
